Security Enhancements

New Features: Usage Guidelines

Support for recursive stop on MovieClip()

It is common for developers to build games comprised of many externally-loaded SWF files containing multimedia assets (either from an application package or downloaded from the internet). Often, these SWFs contain MovieClips that begin playing after they are loaded. On mobile platforms, in particular, there is significant CPU overhead in processing these playing MovieClips even when they are not visible, and it has long been our recommendation to developers to call the stop method on all unnecessary MovieClips after loading a SWF. The new stopAllMovieClips method of DisplayObjectContainer is intended to provide an easier way to accomplish this. It will stop the timeline animations of all MovieClip objects that are descendants of the corresponding DisplayObjectContainer, in addition to the DisplayObjectContainer itself, if it also happens to be a MovieClip.

RectangleTexture class added to Stage3D

The RectangleTexture class is available in the BASELINE and BASELINE_EXTENDED profiles. Unlike a Texture, RectangleTexture allows for non-power-of-two dimensions, but does not support mipmapping, compressed textures, or the 'wrap' sampling mode. It supports the following texture formats: BGRA, BGR_PACKED and BGRA_PACKED. It is intended to be used for 1:1 screen drawing, including backbuffer-sized blits. The maximum size is at least 2048 in the BASELINE profile and 4096 in the BASELINE_EXTENDED profile, or the size of the backbuffer, whichever is greater.

Authoring Guidelines

Authoring for Flash Player 11.8

To use the new Flash Player, you will need to target SWF version 21 by passing in an extra compiler argument to the Flex compiler: -swf-version=21. Directions are below. If you are using the Adobe Flex SDK:

Open the project Properties panel (right-click and chose 'Properties'). Select ActionScript Compiler from the list on the left.

Use the 'Configure Flex SDK's' option in the upper right hand corner to point the project to Flex build 21328. Click ok.

Configure your project to target SWF version 21

Open the project Properties panel (right-click and chose 'Properties'). Select ActionScript Compiler from the list on the left.

Add to the 'Additional compiler arguments' input: -swf-version=21. This ensures the outputted SWF targets SWF version 21. If you compile on the command-line and not in Flash Builder, you need to add the same compiler argument.

Ensure you have installed the new Flash Player 11.8 build in your browser.

Authoring for AIR 3.8Update to the AIR 3.8 namespace

You must update your application descriptor file to the 3.8 namespace in order to access the new AIR 3.8 APIs and behavior. If your application does not require the new AIR 3.8 APIs and behavior, you are not required to update the namespace. However, we recommend all users start using the AIR 3.8 namespace even if you are not yet taking advantage of the new 3.8 capabilities. To update the namespace, change the xmlns attribute in your application descriptor to: <application xmlns="http://ns.adobe.com/air/application/3.8">

Reporting a Bug

Found a bug? Please submit a bug to the Flash Player and Adobe AIR bug database.

Flash Player and AIR may leverage your graphics hardware to decode and play H.264 video. There may be video issues that can only be reproduced with your particular graphics hardware and driver. When reporting an issue involving video, it is essential to note your graphics hardware and driver, along with your operating system and browser (when using Flash Player), so that we can reproduce and investigate issues. Please be sure to include this information as described in Instructions for Reporting Video Playback Issues. Note: Due to the high volume of email we receive, we are unable to respond to every request.
